### Variations

The example below shows the Edit window when a user switches TOG4 to BND. The first x, y, z indicates the first point on the line. The second x, y, z indicates the ending point on the same line. The last value represents the theoretical or actual length of the line.

feature_name=FEAT/LINE,TOG1,BND

THEO/x_cord,y_cord,z_cord,x_cord,y_cord,z_cord,length

ACTL/x_cord,y_cord,z_cord,x_cord,y_cord,z_cord,length

CONSTR/TOG2,TOG3,...,length

The example below shows the unbounded line format:

feature_name=FEAT/LINE, TOG1,UNBND

THEO/x_cord,y_cord,z_cord,i_vec,j_vec,k_vec

ACTL/x_cord,y_cord,z_cord,i_vec,j_vec,k_vec

CONSTR/TOG2,TOG3,...
